Method Detail

onBeforeRender

Called just before a component is rendered only if the component is visible.

NOTE: If you override this, you *must* call super.onBeforeRender() within
your implementation.
Because this method is responsible for cascading Component.onBeforeRender() call to its
children it is strongly recommended that super call is made at the end of the override.

Changes to the component tree can be made only before calling
super.onBeforeRender().
